ST. LOUIS — Steven Jackson has not ruled himself out for the St. Louis Rams’ Monday night game against the Giants. But he hasn’t practiced yet this week and some of his comments made it appear he is already gearing up for Week 3.

Jackson strained his right quadriceps on a 47-yard scoring run on the Rams’ first offensive play of the season during Sunday’s loss to the Eagles.

Jackson said Thursday after pool therapy during practice that the injury had improved.

“It’s all predicated on how I feel on Monday. But definitely shooting to have an outside chance to be able to go,” Jackson said. “Luckily we buy an extra day with the Monday night game but we want to be smart. We know it’s early in the season.”

Coach Steve Spagnuolo says Jackson will be evaluated closer to game day.

“He’s the only guy that knows,” Spagnuolo said. “We’ll see, it’s a day by day thing.”

Spagnuolo said Bradford’s passing was “pretty good,” noting that a few were off the mark.

“But I don’t see him dodging any throws,” Spagnuolo said. “He’s fighting through it right now.”

Jackson says he wants to play in the Rams’ first Monday night appearance since 2006. But he says being 100 percent for the next game — against Baltimore — must be considered.

“You definitely want to be out there, but I would be the first one to tell you if it was just a Sunday regular game it would still kill me just as much,” Jackson said. “This is a big game. It just kills me to know my team needs me and I’m not able to be out there and answer the call.”

The Rams added quality backups for Jackson for the first time in free agency, signing Cadillac Williams and Jerious Norwood. Williams had 91 yards rushing and 49 yards receiving in the 31-13 loss to Philadelphia, and Norwood, who’s been used more in the return game, had 10 yards on 3 carries.

Jackson said that helps “ease the decision.”

“I do have fully 100 percent trust that Cadillac and Jerious can get the job done,” Jackson said. “That assures me that I can if I needed to, take a week off.”

Wide receiver Danny Amendola reported good progress already after dislocating his left elbow in the fourth quarter when he tried to brace his fall after a catch and the arm buckled. Amendola curled into a ball as tacklers and teammates surrounded him, and TV elected not to run a replay to spare squeamish viewers.

Amendola denied a rumor he had lobbied to play this week, but already has range of movement and wouldn’t rule out Game 3.

“I’ve been healing pretty fast, it’s just the severity of what happened inside,” Amendola said. “I’ll be back soon enough.”

Spagnuolo said it’s tough to hold Amendola back.

“You put a timetable on Danny Amendola, he’s going to make us all look wrong,” the coach said. “He wants to jog, he wants to do everything. You’ve got to protect him from himself a little bit.”
